Underground Neutrino Observatory Operation - Chin

File photo dated on October 10, 2025 shows staff members working on a stainless steel truss of the central detector of the Jiangmen Underground Neutrino Observatory (JUNO) in Jiangmen, south China's Guangdong Province. The world's largest transparent spherical detector began operation in China on Tuesday, making it the world's first operational ultra-large scientific facility dedicated to neutrino research with ultra-high precision. Having completed the filling of its 20,000-tonne liquid scintillator detector, JUNO in Guangdong began taking data after more than a decade of preparation and construction, on August 26, 2025 in Beijing, China.

World's Largest Neutrino Observatory - China

Qin Zhonghua works at the construction site of the Jiangmen Underground Neutrino Observatory (JUNO) in Jiangmen, south China's Guangdong Province, Oct. 9, 2024. China has constructed the world's largest transparent spherical detector 700 meters underground to capture elusive neutrinos, often dubbed "ghost particles," to unravel the secrets of the infinitesimally small and the infinitely vast in the universe. The 12-story-tall acrylic sphere with a diameter of 35.4 meters, buried deep in a granite layer of a hill in Kaiping, Jiangmen City in south China's Guangdong Province, is the core part of JUNO, a gigantic and complex scientific facility. The construction of the challenging project, launched by the Chinese Academy of Sciences (CAS) and the Guangdong government in 2015, has entered the final stage. Installation of the entire device is expected to be completed by the end of November, and the full operation of the facility is scheduled for August 2025, according to the Institute of High Energy Physics (IHEP)
